Detection and extraction technology of CW radar life signal
摘要
Abstract
As the radar life signal is weak,it is often submerged in the noise.Because of non-sta-tionary and randomicity of these clutter signals,it is necessary to denoise efficiently before ex-tracting and separating useful signals.This study improves the radar life signal’s theoretical model of the continuous wave,processes de-noising by introducing lifting wave transform and de-termines the best threshold function through comparing the de-noising effects of different thresh-old functions.The result indicates that both SNR and MSE of the signal are better than the tradi-tional ones by using lifting wavelet transform and combining with a newly improved method for soft threshold function de-noising.关键词
